Method and Apparatus for Requesting Media Replication in a Collaborative Communication Session, and Method and Apparatus for Assigning a Communication Medium for a Collaborative Communication Session

1. A method comprising: identifying, by a controlled terminal in a collaborative communication session, that a media portion of the collaborative communication session is to be replicated to a second terminal; generating, by the controlled terminal, a message that includes an identification of the second terminal; and transmitting, by the controlled terminal, the message to a server of the collaborative communication session.

2. The method of claim 1 , wherein the message is a session initiation protocol (SIP) message.

3. The method of claim 2 , wherein the message is a SIP REFER message.

4. The method of claim 2 , wherein the server is an internet protocol multimedia subsystem (IMS) application server (AS).

5. The method of claim 1 , wherein the media portion is an audio media portion, a video media portion, or a text media portion.

6. The method of claim 1 , wherein the controlled terminal is a computer or a mobile telephone.

7. A controlled user equipment (UE) comprising: processing circuitry to: identify, when the controlled UE is a controlled UE in a collaborative communication session, that a media portion of the collaborative communication session is to be replicated to a second UE; generate a first message that includes an identification of the second UE; identify, after generation of the first message, a second message that includes an indication that the media portion of the collaborative communication session is replicated to the second UE; identify, after the identification of the second message, that the media portion of the collaborative communication session is to be replicated to the controlled UE; generate, based on the identification that the media portion of the collaborative communication session is to be replicated to the controlled UE, a third message related to a request for information regarding the collaborative communication session; and generate, based on the generation of the third message, a fourth message that includes an identification of the controlled UE; transmitter circuitry coupled with the processing circuitry, the transmitter circuitry to transmit the first message, the third message, or the fourth message, to a server of the collaborative communication session; and receiver circuitry coupled with the processing circuitry, the receiver circuitry to receive the second message from the server.

8. The UE of claim 7 , wherein the first message, second message, third message, and fourth message are session initiation protocol (SIP) messages.

9. The UE of claim 8 , wherein the first message is a SIP REFER message.

10. The UE of claim 8 , wherein the second message is a SIP re-INVITE message.

11. The UE of claim 8 , wherein the third message is a SIP SUBSCRIBE message.

12. The UE of claim 8 , wherein the fourth message is a SIP REFER message.

13. The UE of claim 7 , wherein the processing circuitry is further to identify, based on the generation of the third message, a fifth message that includes information related to the request for information.

14. The UE of claim 13 , wherein the fifth message is a SIP NOTIFY message.

15. The UE of claim 7 , wherein the fourth message further includes a SIP address of the server, an indication of the media portion of the collaborative communication session to be replicated to the controlled UE, or a call identification for the collaborative communication session.

16. The UE of claim 7 , wherein the first message further includes a SIP address of the server.

17. The UE of claim 7 , wherein the server is an internet protocol multimedia subsystem (IMS) application server (AS).

18. The UE of claim 7 , wherein the UE is a computer or a mobile telephone.

19. The UE of claim 7 , wherein the media portion includes an audio media portion, a video media portion, or a text media portion.

20. The UE of claim 19 , wherein the UE further includes a graphics processor coupled with the processing circuitry, the graphics processor to output the video media portion to a display of the UE.
